Hardening Technology

Non-linear Shaft Hardening

Non-linear Shaft Hardening
Scan hardening using circle coils cannot keep the coil gap constant, resulting uneven hardening.
Our semi-open coil built to the part’s dimensions creates an even casing.
By generating current in the axial direction, even the difficult corner areas are sufficiently hardened.

Crankshaft Low-Warpage Fillet Hardening

Crankshaft Low-Warpage Fillet Hardening
Fillet hardening is more prone to warpage than conventional flat hardening. Our advanced technology, supplied to customers around the world, keeps warpage to a minimum.

Camshaft Hardening

Camshaft Hardening
The coil tracks the rotating cam to create an even case depth and stable residual stress over the entire cam surface. Our method prevents nose cracking from overheating and post-process grinding, increasing line productivity.

Large Parts and Gear Hardening

Large Parts and Gear Hardening
By heating in two steps, we achieve deep case depth in short cycle time for large parts while preventing overheating and warpage.

Linear Guide (Rail ) Hardening

Linear Guide (Rail ) Hardening
Linear guides and other long parts bend during hardening, affecting the coil gap and resulting in uneven case depth.
In our system, the support roller minimizes warpage during hardening while the coil tracking system keeps the coil gap constant.
